DFU issues on iOS with nrfconnect and pca10040 using SDK 15.3 example binary

[TomKeddie]

Hi,

We're seeing DFU issues on iOS that we're not seeing on Android.  To make things simpler I've reproduced the problem with pca10040 and nrfconnect for iOS.

I'm using nrfconnect 2.0.3(53) on iOS 13.1.3.

I'm using the pre-built bootloader_secure_ble_debug_without_bonds_s132.zip from SDK 15.3 on a pca10040 devel board.

On android I can use nrfconnect to repeatedly update the board with no problems.

On ios I get a message "The connection timed out unexpectedly" almost immediately after selecting start.  We see the same issue with our app/firmware/hardware.

Thanks,
Tom

Hi Tom, 

can you upload the debug output log from the bootloader and the log from nRF Connect on iOS?

Best regards
